CH ECK STRAP FOR DOORS.

Application filed "December 6, 1924. Serial No. 754,289.

Our invention relates to checks for swinging doors whereby the door maybe prevented from being swung too far outwardlyon its pivot or hingethereby avoiding possible injury or breakage to the pivot or hinge orother connection.

The principal object of the invention is the production of a door checkof the character described which shall be of simple construction andwhich shall not interfere with the normal-closing of the door.

A further object of the invention is the production of a door check ofthe character described which maybe shipped as a unit whereby theinstallation thereof is facilitated.

Still a further object of the invention is the production of a doorcheck of the above character which shall 'be provided with a bumper ofsimple and novel construction adapted to absorb the shock of tooforceful an opening of the door thereby obviating injury to its'hinge orpivot.

Other and further objects and advantages of the invention will appearfrom the accompanying description, the invention consisting in the noveldoor check hereinafter more particularly described and then specified inthe claims.

In the accompanying drawing illustrating a practical embodiment of theinvention:

Fig. 1 is a perspective view of the device as applied to the door andone of its frame members showingthe door in open position.

Fig. 2 is a similar view showing the door in closed position.

Fig. 8 is a side elevation of the device per se.

Referring in detail to the several figures of the drawing:

1 indicates a portion of a side of a door or a side member thereof while2 indicates the adjacent stationary wall or frame to which the door ishinged or pivoted as by the hinge 3. The door 1, on the inner facethereof at the meeting edge of that face and the adjacent forward face,is provided with a cut-out portion or squared slot t while the frame 2on the inner face thereof, also at the meeting edge of that face and theadjacent forward face, with an elongated cut-out portion or slot 5.Fastened to the forward face ofthe door 1 by suitable screws orotherwise is plate 6 of the door check. Said plate is provided with alateral perforatedflange 7 extending at right angles thereto into theslot 4. 1 i

8 indicates a wire strap the upper end of which extends through theperforation in the flange 7. and is provided with a head 9' therewithand passing through suitable openings in the frame 2. The outer ends ofsaid extensions are screw-threaded as shown and receive nuts 13, saidextensions being also provided with collars 14c to prevent-said eX-tensions from being pulled too far through the openings in the frame 2whereby the rod 11 will be rigidly held in position, as is obvious, when*the nuts are tightly screwed against the outer side face of the frame2.

The lower end of the wire strap 8 is looped as at 15 and is adapted toride on therod 11. 16 indicates a compression spring coiled around theupper part of the rod 11, the upper end of which is fastened to theupper collar 1 1 or to a point adjacent said collar. Said compressionspring is adapted to be engaged by the loop 15. If so desired theopening 4: at one side and the plate (3 may be covered and hidden fromview by a plate 17 extending across the door and forming a part of awall thereof while the opening 5 may be also covered and hidden fromview by any suitable covering (not shown).

Assuming the door to be closed or in the position shown in Fig. 2, itwill be noted that the wire strap 8 extends downwardly intermediate theslot between the door and its frame 2, it being enabled to assume thisposition because of the bend 10. lVhen in this position the loop 15assumes a position adjacent the lower end of the rod 11. When the dooris opened the loop 15 rides upwardly on the rod 11 until it strikes thespring 16 compressing it upwardly, said spring acting to absorb theshock of the opening thereby preventing a possible injury to or breakageof the hinge 3. As the door is opened 2 V reoaeee the upper end of thewire strap 8 will rotate in the perforation in the flange 7 in anobvious manner.

What we claim as our invention is 1. In an apparatus of'the characterdescribed, a wall, a member swingingly secured thereto and a check straconnected to said wall and said member and having one end adapted torotate while the other end simultaneously effects a vertically slidingmovement when said member is swinging from or towards said wall. 7

2. In an apparatusof the character described, a wall, guiding meansthereon, a member hinged to said wall, a wire check strap secured tosaid member and said guiding means and capable of a vertical slidingmovement on said guiding means and a spring on said guiding meansadapted to be compressed by said check strap when said member is swungon its hinge, ,aid check strap lying in a substantially verticalposition intermediate said wall and a side of said member when saidmember is in closed position.

3. In an apparatus of the character described, a wall, a door connectedto said wall and adapted to be swung away there from and a wire checkstrap connectedto said wall and door to limit the swingiiig movement o1said door and capable of arotary movement at one connection and asliding movement at the other, said check strap being also adapted tolie intermediate the space between said wall and door when the door isin closed position adjacent the wall.

4. In an apparatus of the character described, 21 wall, a swinging doorhinged thereto, a plate on said door, a vertically extending rod securedto said wall and a wire check strap connected to said plate and capableof a sliding movement on said rod and adapted to limit the movement ofsaid door, said check strap lying in a substantially vertical positionintermediate said wall and a side or" said door-when said door is inclosed position.

5. In an apparatus of the character described, a wall, a door hingedthereto, a perforated plate fastened to said door, a verticallyextending rod secured to said wall, and a wire check strap having oneend extending through the peri o-rationin said plate and the other endlooped around said rod and capable of a sliding movement thereon;

6. In an apparatus or" the character 'described, a wall, a door hingedthereto, a per- -torated plate fastened to said door, a rod secured tosaid wall, a wire check strap having one end extending through theperforation in said plate and provided with a head thereon and the otherend looped around said rod and capable of a sliding movement on said rodand a bend in said check strap adjacent its headed end.

7. In an apparatus of the character described, a wall provided with aslot therein,

a door hinged to said wall and provided with a slot therein, a platemounted in said slot in said door, a rod mounted in said slot.

in said wall. and a wire strap connecting said plate and said rod andadapted to limit. the swinging movement of said door.

8. ln an apparatus of the character described, a wall, a swinging doorhinged thereto, a vertically extending rod on said wall provided withextensions extending therethrcugh, means carried by said extensions forholding them to said wall, a spring on said rod and a check strapconnected to said door a? d slidably mounted on said rod.

9. in an apparatus of the character described, a wall, a member hingedthereto and a check strap connected to said wall and said member havingone end-thereof adapted to rotate while the other end issimultaneouslymoved vertically when said member is moved on its hinge.
